Technical Services
Evidence-based assessments from a geologist who has seen it all — from grassroots discovery to resource definition, across the world's gold-rich landscapes that are increasingly shaped by artisanal and small-scale gold mining (ASGM).
Gold Project Evaluations & Due Diligence
Whether you are a fund group assessing a proposed joint venture, a private investor considering entry into a new gold mining district, or a company requiring an independent second opinion on a resource, Mynah Exploration delivers rigorous, impartial technical assessments.
Evaluations draw on decades of direct field experience in gold-bearing laterite, oxide, and primary ore systems across more than 30 countries. Historical data is compiled, geological models constructed and critically assessed, resource estimates are scrutinized, and jurisdictional risk is evaluated — all delivered in clear language that supports sound decision-making.
All engagements are strictly confidential. Past evaluations have included world-class gold deposits in Africa and South America, gold exploration projects in PNG, copper-gold porphyry projects in the Middle East, gold mines in Egypt, and emerging gold districts in West Africa.
Tropical Laterite Regolith Expertise
The tropical laterite regolith is one of the most misunderstood environments in gold exploration. Deeply weathered, chemically complex, and host to significant supergene gold enrichment, it requires specialist knowledge to interpret correctly.
Danae Voormeij is among the world's leading experts in laterite gold exploration. She has designed and trained field teams for soil sampling programs across Madagascar, Uganda, Liberia, Nicaragua, Papua New Guinea, the Philippines and Suriname.
3D Vein Modelling
For clients holding gold mining assets, understanding the three-dimensional geometry of ore-bearing vein systems is critical to mine planning, resource estimation, and maximizing gold recovery.
Danae Voormeij has undertaken implicit 3D vein modelling for gold mine owners in Kenya and Zimbabwe, using Micromine to construct detailed geological models from historical underground drilling, channel sampling, and underground mapping data. The result is a dynamic, navigable 3D model that reveals vein continuity, plunge directions, grade distribution, new veins(!) and structural controls on mineralization — giving mine owners and investors a powerful tool for decision-making.
The flythrough video above shows an extensive hand-modelled vein system for the historic Venice Mine Complex in Zimbabwe, with historic surface gold workings shown in red, illustrating the relationship between artisanal mining activity and the underlying vein architecture.
Interpretation of Artisanal and Small-Scale Gold Mining (ASGM)
Artisanal and small-scale gold miners are the best prospectors in the world. Understanding where they dig, why they dig there, and what it means geologically is a powerful and underutilized tool in formal exploration.
Danae Voormeij is an internationally recognized expert in interpreting artisanal mining patterns in tropical terrains — both dry savanna and wet rainforest environments. She can assess what artisanal activity reveals about the underlying gold system, helping exploration teams prioritize targets and avoid costly misinterpretations.
Field Team Training
Laterite soil sampling is a precise discipline. Consistent, correct horizon identification is what turns raw soil into discovery data.
Danae works directly on-site with exploration field teams — geologists and technicians alike — teaching correct soil horizon identification, sample collection protocols, and regolith logging. Training has been delivered across Africa, Southeast Asia, and Latin America, and is tailored to each specific jurisdiction and terrain type.
